MILK-CAN.

Specification o1 Letters Patent.

Application filed Aug-ust 22. 1910.

Serial No. 8,270.

To all echo/m, Il may con/rra.' y

Bc it known that l, (hun. H. ZwauMANN. u citizen ot the United States, residing at the cityof Kalamazoo, county of Kalurmr zoo, State of Michigan, have invented ccrtain new and` useful Improvements in Milli Canswof which the following is a specifica tion.

This invention relates to improvements in milk cans.

The objects ot' this invention are: First, to provide an improved seamless milk can. Second, to provide au improved construction of milk can, which lwill have a very smooth interior, with curved surfaces only presented, whereby the can is entirely sanitary and cleanly. Third, to provide an improved construction of .milk can. which lends itself readily tothe Welding process for organizing the same. Fourth, to provide an improved bottom for such a milk can. Fifth, to provide an improved cover for such a milk can.

A still further object is to provide a milk.

can, which can be .very readily enameled on account of the joints being` welded joints and entirely smooth, lso that the enamel can spread over the same.

Further objects, and objects; relating 1o details, will readjly appear from `the description to follow.

I accomplish the objects of my invention by the devices and means described in the following, specification.

The invention is clearly defined and pointed out in the claims.

A structure, which is apreferrcd embodiment of myinvention, is clearly illustrated in the accompanying drawing, forniinpl a lpart of this specification, in which:

Figure l is a detail View, partially in section, of a .milk can ex'nbodyingg` the features ot .my invention. Fig. 2 is a vertical scar tional View through the central part ot' the various blanks` of sheet metal. `from which my improved can is constructed. Fig. 3 is an inverted plan view of the can vas illustrated in Fig. .2. Fig. 4 shows an ordinary milk can cover in position in my inn roved milk can ncclt.

ln the drawing, similar numerals o' reference :refer to .similar parts throughout the several views.

The` can ie made up o't' several parte assembled together und Welded, either by elec tric welding. or by oxyhydrogen welding,

oxj'hydrogen beingr the preferred method.

The bottonrl ot the can ismade or drawn out of a single piece ot' sheet metal with the bottoni nicely rounded und convex to make every portion of the sameconreniently accessible on' the inside and very strong. The upper edge of this bottom is flanged,v slightly outward at lvl in the process of' is rovi'lcd with an opjiosing [lange 9. for

we dingr to the [lange 1il of the bottom. The breast 3 of the can is rounded and termit mites .in a flange 3 at its` upper end, being atout-ed Apr. 22, 1913.` i

'mamifacturo The upper part 2 of the can' 65 also slightly outturned. The neck 4 of the'70 l cunis formed ot a separate piece, formed with a shoulder 5, for contacting with my improved coverto make a tight joint at.` that point., and flanged outwardly into. a

bead 3 at its outer upper edge. The lower 75 end of this neck is provided with an out` wardly-turned flange 4 for welding.,r t0 the flange 3 above the breast of the body por tion ot' the can. By this arrangement and construction, it will be seen that the joints 39 between these various parts can be very readily welded by the oxyhydropenlmethod,-

und, owing to the fact that the,` milk can mouth is of considerable size, the joints can be welded both outside and inside. V joint can then be smoothed down by any suitable grinding and polishingr means, and the can can then` becoated withlenamel; This could not .he done if the parts were brazcd togethen'because the extreme heat 90 used in applyingV the enamel would melt` the solder.

The handles 7 are secured to the outside ot' the can by electric Welding, the method i pursued being known us the point welding ,95

method.

.The can cover 8 is provided with a shouldered portion 9 corresponding to the shoulder 5 in the neck of the can andit termi The 853 notes in a rim 10 at the top, whereby `the 10 same can be conveniently handled.` The cover is held in place by a clamp 11, which urges thc cover down and makes a tight joint `between the shoulder portions 5 and 9.

Around the bottom of the can is a heavy lo rinpr `ll, which closely lits the bottom of the can at l-l and has lingers or lugs 15 struck in from the same, which are welded securely to the bottom of the can. When this is done,`

the can is coated outsile and in with enamel, no

coating 17 on the inside.

the outside and the The can may also be coatedfwith tin and Will be very eective. Having'thus described my invent-ion, what I claim as new and desire to secure by Letters Patent, is:

1. A milk can constructed of a bottom portion rounded and convex, and a top portion, also rounded at the brest, with a suit,u able welded joint between; a. hoop around the bottom of the said can with ingers struck in and joined to said bottom; a'. neck for the said can with a suitable Welded joint connected to the body of siid can; as specied y 2A milk can constructed of a bottoniy the coating 1.6 beingon "portion rounded and convex; and a top portion, also rounded at the breast, with-a suitable Welded joint between; e hoop around portion rounded and convex, and a top portion, also rounded at the breast, with a suitable Welded joint between; a hoop around the bottom of the said can with ngers struckjn and joined to said bottom, is specified. l

nwitness whereof, I have hereunto set my hand and seal in the presence of two witnesses. v v
